Nobel Laureate Lars Peter Hansen Studies Transition to Carbon-Neutral Economy

Join the Department of Applied Mathematics in welcoming Nobel laureate Lars Peter Hansen, David Rockefeller Distinguished Service Professor in Economics and Statistics, University of Chicago as he delivers “How Should Climate Change Uncertainty Impact Social Valuation and Policy?” in room 104 of the John T. Rettaliata Engineering Center from 1:50 p.m. to 2:50 p.m. April 15.


We study the uncertain transition to a carbon-neutral economy. The requisite technological innovation is made more probable through research and development (R&D). We explore multiple channels of economic and geoscientific uncertainties that impact this transition, and we show how to assess the relative importance of their varied contributions. We represent the social benefit of R&D and cost of global warming as expected discounted values of social payoffs using a probability measure adjusted for concerns about model misspecification and prior ambiguity. Our quantitative results show the value of R&D investment even when the timing of its technological success is highly uncertain.
